Interface AND Content Translation Block

It seems like the Langauges block provided by the module translates ONLY the inteface.
To translate both the Content & Interface create a new PHP block and use the following code:

  <?php //get listed links of languages
      $query = drupal_query_string_encode($_GET, array('q'));
      print theme('item_list', translation_get_links($_GET['q'], empty($query) ? NULL : $query));
  ?>

Perphaps this should be applied to module's code as well. I just don't know how to create a patch...
